PROBLEM TO BE SOLVED: To provide a resonator equipped with a temperature compensation function. SOLUTION: A pair of temperature-compensated resonators (300, 390) include a first resonator (111) which is composed so as to resonate with a first frequency (f01) and has a first frequency-temperature coefficient (TC1), and a second resonator (121) which is composed so as to resonate with a second frequency (f02) and has a second frequency temperature coefficient (TC2). The second frequency (f02) is higher than the first frequency (f01) and the second frequency-temperature coefficient (TC2) is smaller than the first frequency-temperature coefficient (TC1). The first resonator (111) and the second resonator (121) are formed on the same substrate (306). COPYRIGHT: (C)2007,JPO&INPIT
